Lee the differences are obvious,In the old days the carburator was known as a mixing valve,Today it has to have an exact proportion of air/fuel mixtures to keep a balance of it working properly.Like a 14 to 1 ratio,The equation works out like this 14 parts air to 1 part fuel,vacuum in the intake manifold pulls the fuel down and the combustion process begins.Fuel injection is a great concept but they too are subject to the maladies that their carburated systems have too like clogged injectors,poor running,hard to start.When carburators get dirty they too will not work well,those tiny,jets in them get dirty and then on a cool or cold morning they are a bear to start.My suggestion to all of you out there that have either systems is to have them professionally cleaned out if you can't afford it then try 3 cans per month of barryman carburator/fuel injector cleaner,it'll get you by for at least awhile until its time to have it overhauled down the line.

No, carburator's work on vacuum pulling fuel in from the top of the intake manifold and mixing before it reaches the valves.
Fuel injection has "injectors" mounted right next to the valves after the intake manifold. It "shoots" a set amount of gas directly into each cylinder as the valve opens, the air comes in with it.
Fuel Injection is more efficient

A carburetor is a device for mixing fuel and air for an engine. It uses the vacuum created by the piston moving down to draw in air. Fuel is sprayed into the moving air as a mist, and it mixes in the intake manifold before being drawn into the cylinder.
A fuel injector uses pressure to push the fuel spray into the cylinder. It's much more precise, as the amount of air/fuel mixture can be metered and changed according to ambient conditions - air pressure and temperature, how much power is needed, etc.

no the carburator just constantly takes the gas while the fuel injector only takes the right amount of gas your car needs, saving you money

Only in function. A carburator does not have an exact dosage meter that depends on your driving method.

Injectors squirt the gas in.
Carbs get the gas sucked out of them by the vacuum caused by the piston on its downward 'intake ' stroke.

same function (mixing aspirated fuel with air) but very different technologies.

Michael has got it. no more to explain.
